Title: Improvements in and relating to the Control of Electric Motors.
IPC: H02P1/20
Filed: 1909-03-04
Granted: 1909-06-10
Abstract: 5318. Allgemeine Elektricitõts-Ges. March 4, 1908, [Convention date]. Systems for continuous-current motors only.-In a control system for dynamoelectric machines, automatic switches for cutting-out resistance sections are governed by overload devices which operate to re-insert resistance. The resistances r<1>, r<2>, r<3>, r<4> are shown connected in series with the armature a of a motor, and are short-circuited by switches s', s<2>, s<3>, s<4> as the back electromotive-force rises. A switch m is arranged with contacts c in the actuating - circuit of the resistance switches and its actuating-coil in the motor circuit. When the armature current is too heavy, the switch m operates, and any of the resistance switches that happen to be closed are then opened, and they remain open until tho current falls sufficiently to permit the switch m to close. The switches s', s', &c. may be opened by short-circuiting the actuating-coils, instead of by opening the actuating-circuit. A resistance w may be permanently included in the motor circuit if the current oscillations are frequent. In a modification, the automatic switches are provided with series coils o', o', o<3>, o<4>, Fig. 2, arranged to oppose the actuating-coils, and to open the resistance switches if the current rises above a predermined value. The series coils may operate to shortcircuit or to open-circuit the actuating-coils. In another modification, the actuating-coils are energized by a constant potential, and are arranged so that the circuit of each coil may be broken by switches operated by coils carrying the motor current. Weights or springs may be used instead of electro-magnets to hold the resistance switches closed.

Title: Improvements in and relating to Machines for Affixing Stamps, Labels and the like.
Inventor: HADIDA HENRY
IPC: B65C11/04
Filed: 1909-03-06
Granted: 1909-07-08
Abstract: 5477. Hadida, H. March 6. Stamp-applying.-Relates to machines of the type described in Specification 11,608/07, in which stamps &c. are cut from a strip and affixed on the depression of a spring-returned plunger. The plunger a is provided with a pawl g pivoted at h and provided with a spring which maintains it in an horizontal position. The pawl is serrated at its free end, and rides over a fixed ratchet-bar i when the plunger is depressed. If the plunger is released before the downward stroke is completed and a stamp sheared off, the pawl g engages the ratchetbar i, and prevents the return of the plunger. Below the slot j, through which the stamps are fed, are a pair of L-shaped arms k which prevent the stamp from curling towards the moistening- pads l. These arms are held in position by springs on their hinge-pins, and are displaced laterally by the plunger in its descent. The shearing-blade n is hinged at n<1> to the machine frame, and its opposite end is forked, the lower fork arm being shorter than the upper, which is arrested by a ramp p when the cut is completed. The shear-blade is operated by a stud q mounted on a spring arm on the plunger, and the stud q is pressed flush into the plunger when it strikes the ramp p, so that the plunger continues its descent. When the plunger returns, the stud q is again pressed into the plunger by the ramp p, and enters the slot o in the knife on passing the ramp. An improved dash-pot device comprises a cylinder r connected by two rods r<1> to the plunger. The cylinder moves about a fixed piston t, and is fitted with a small air passage, the size of which is controlled by the point of a screw. By this means, the greatest opposition is afforded at the beginning of the forward feed of a stamp, when the spring returning the plunger is most compressed, and a smoother feed is thus obtained.

Animal traps; animals, catching and destroying.-A trap for catching hares, rabbits, and other animals without injury, consists of a frame 1, Figs. 2 and 3, of wood or the like fixed firmly in the ground by spikes 2 and provided with two platforms 3 which are hinged to the frame as at 4. The platforms are held flush with the frame by springs 5, and their downward movement is limited by curved stops 6. Hoods 7 of suitable material are fixed to the frame 1 and also to spring-controlled frames 9, which are secured to the frame by plates 12. The hoods are retained in the open position by flexible strips 16, attached at one end to the frames 9 and provided at the other end with a hooked clip or eyelet-piece 17, which engages with a pin 18 fixed to the underside of opposite platforms 3. The trap when set is preferably covered with light undergrowth or the like. When an animal steps on to one of the platforms, the opposite hood 7, by the release of the piece 17, is released and is raised to the vertical position. Any attempt at retreat brings the animal on to the opposite platform whereupon the second hood 7 is likewise moved into the dotted position shown in Fig. 2, thus trapping the animal without injury. When the trap is required for capturing ferocious animals, the frames 9 may be locked in the sprung position by spring catches. By reversing the position of the hinges 4, a trap for birds and animals is provided.

Title: Improvements in Obtaining Tetrachloride of Tin from Tin Scrap and other Materials Containing Tin.
Inventor: WOLFF PAUL
IPC: C01G19/08
Filed: 1909-08-09
Granted: 1910-08-09
Abstract: 18,329. Wolff, P. Aug. 9. Stannic chloride is obtained from tin-plate clippings and other materials containing tin by treatment with undiluted chlorine in the absence of air. The reaction vessel is exhausted of air, or the air is expelled by admitting chlorine at the bottom and drawing off the air at the top. The chlorine valve is so controlled that a reduced pressure is maintained in the tank, which is indicated by a pressure-gauge. This retards the reaction sufficiently to prevent the temperature from rising high enough to allow the iron to be attacked. The stannic chloride collects in liquid form at tho bottom of the tank, and may be drawn off when the chlorine ceases to be absorbed and the pressure in the tank therefore rises. The remainder of the chloride is then distilled off under a reduced pressure, which is lower than the reduced pressure employed in the chlorination process ; or the whole of the chloride may be so distilled. The distillate is practically pure and free from chlorine. Specification 25,496/07 is referred to. The Provisional Specification also states that stannic chloride may be purified from free chlorine by distillation under reduced pressure.

Title: Improvements in and relating to Fluid Meters.
IPC: G01F1/37
Filed: 1909-10-06
Granted: 1910-09-22
Abstract: 22,804. British Thomson-Houston Co., [General Electric Co.]. Oct. 6. Gas, air, and steam meters.-Improvements in fluid meters of the type in which a U- shaped movable vessel contains liquid, the surfaces of which are subjected to different pressures, thereby causing the liquid to be displaced and the vessel to be moved against a returning force, such movement being utilized to measure the flow of fluid, comprise the provision of motion - multiplying mechanism connected to the U-shaped member, and also the use of means for reducing irregularities due to the varying pressures of the fluid. The cups 19, 20 and connecting- pipe 21 forming the U- shaped vessel are supported by the beam 18 on a suitable support 13. Pressure is admitted to the cups by flexible metal conduits 22, 23, which are connected with the low and high pressure parts of a Pitot plug respectively. The motion-multiplying mechanism comprises a lever 27 supported on a knifeedge 34 and connected at one end with an extension 29 on the bridge 18. The other end is attached to a bell-crank lever 35, which actuates the indicator pencil 39 through a light arm 38. The pen moves over a rotating drum 40 carrying a scale or chart, which is held thereon by a spring-pressed roller 44 and is fed through to an opening in the casing by pins 43 which engage perforations in the paper. To oppose the tilting of the vessel, a weight 48 is suspended on the arm 49 so that its effective movement increases as the arm is moved away from the vertical. The position of the weight 48 on the arm 49 may be altered to cope with changes in the conditions of the flowing fluid. For this purpose a coiled tube 50, similar to a Bourdon tube, is fixed at one end to a support 50<a>, and is connected with the main or pipe through which the fluid to be metered flows. The other end is attached to a lever 52, from the end of which passes a silk thread 56 to a small pulley 57. From a large pulley 60 passes a thread 61 to the weight 48, which is balanced by a weight 59. As the pressure in the main alters, so the weight 48 is moved to and from the axis 37. The Pitot plug, shown in Fig. 6, comprises two concentric pipes, the outer one constituting the high-pressure part having a number of orifices facing in direction opposite to that of the flowing fluid, and the inner one constituting the low-pressure part. The flexible connectors have semicircular ends 75 of circular cross-section and flattened sides 76.
